Parameters
278
It is available for all hardware configurations in Termination mode.
This test verifies that the SYS-RX enables the termination with in the
required time.
The data generator sends Burst-mode SYS CJTPAT signaling with nominal
amplitude settings while the DUT is configured for Terminated-mode.
Then, the T
TERM-ON-SYS-RX
is measured using a real-time oscilloscope. Among all measured
T
values, the maximum and minimum T
TERM-ON-SYS-RX
values are considered as the final results.
The test will pass if the maximum T
PREPARE time defined by the DUT´s LS_PREPARE_Length_Capability
attribute (see
Table
42).
This test is performed at each selected lane.
Refer to the connection diagrams shown in the Connection Diagram
section of the Test 2.1.4-HS-RX Differential Termination Enable Time test.
The parameters used in Expert Mode for this test, are as follows:
•
